SiC power semiconductor modules

Paul Boughton

Mitsubishi Electric Corporation has launched of three types of silicon carbide (SiC) power modules for home appliances, industrial equipment and railcar traction systems.

The modules, which use schottky-barrier diodes (SBD) made with SiC, are expected to reduce the size, lower the weight and raise the efficiency of inverters in power electronics devices.

In recent years, inverters have come to be used in a wide variety of applications, including home appliances such as air conditioners and refrigerators, as well as industrial equipment and railcar traction systems.

Power semiconductors utilising SiC can dramatically decrease power loss and enable high-speed switching, which is raising expectations from the point of view of energy efficiency
